2. Locate and replace faulty relay (See Figure 4-13). See Chapter 6 of the
manual for recommended replacement relays.
3. Perform a system Reset to clear Alarm.
Diagnostics
Each CPU performs both off-Line and on-line diagnostics. Off-Line diagnostics
are performed at power-up or when the CPU’s Reset switch is toggled. On-Line
diagnostics are performed when the CPU is in its normal operational mode,
under application-program control.
Off-Line Diagnostics
The following list shows the tests run by Off-Line diagnostics, and the order in
which they are run. Off-Line diagnostics are started immediately after a CPU
Reset switch is toggled. If during a diagnostics routine, a particular test fails,
testing is stopped and the failure annunciated, through the Fault LED and
engineering workstation. If an engineering workstation is not connected to the
control at that time the failure is stored for later reading. When a fault is detected
by a diagnostics routine, the CPU module’s Fault LED will periodically repeat
bursts of flashes; the number of flashes in each burst indicates the test that
failed. If the CPU module’s Fault LED flashes replace the module.
Table 5-1. Off-Line Diagnostic Messages
Flashes In Burst Error Detected
1 Start Up test failed
2 Control Status Register test failed
3 DUART test failed
4 Local RAM test failed
5 Local RAM Misaligned test failed
6 Flash Memory test failed
7 Clock Interrupt test failed
8 VME Bus Timeout test failed
9 EEPROM test failed
10 Floating Point Math Co-processor test failed
11 Real-Time Clock failed
On-Line Diagnostics
As soon as the application program starts running, the system will use a small
portion of run time to continuously run on-line diagnostic tests. A failure of any
one of the on-line tests results in the I/O lock being asserted and display of a
message in the PCI’s OpSys Fault mode, as shown in Table 5-2. If the CPU
module’s I/O Lock LED stays on during normal operation replace the module.
